9.1.3 Vibration
Sine-shaped vibrations occur in stationary use; depending on their intensity,
they have different effects on the robustness of the motors.
The robustness of the overall system is determined by the weakest component.
Based on DIN EN 60721-3-3 and DIN EN 60068-2-6, the following values result
for Rexroth motors:
Direction
Maximum permissible vibration load (10-2,000 Hz)
Encoder S1, M1 Encoder S2, M2
axial 10 m/s² 10 m/s²
radial 30 m/s² 10 m/s²

9.1.4 Shock
The shock load of the motors is indicated by providing the maximum permitted
acceleration in non-stationary use, such as during transport.
Damage to functions is prevented by maintaining the limit values specified.
Based on DIN EN 60721-3-3 and DIN EN 60068-2-6, the following values result
for Rexroth motors:
